A high-frequency heating apparatus comprises a power supply including a commercial power supply or a battery, a frequency converter for converting the power of the power supply into high-frequency power, a boosting transformer for increasing the voltage of the output of the frequency converter, and a magnetron for receiving the output from the boosting transformer. The apparatus further comprises a shield member made of a non-magnetic conductive material and forming a substantially electrical open loop in the winding direction of the primary winding between the primary and secondary windings of the boosting transformer. The shield member is connected to the core or the housing of the boosting transformer thereby substantially containing a high- voltage circuit in the shield space. High safety of the high-frequency heating apparatus is thus assured without grounding the housing.
